A Multi-Scale Analysis Of Jaguar (Panthera Onca) And Puma (Puma Concolor) Habitat Selection And Conservation In The Narrowest Section Of Panama., Kimberly A. Craighead
A Multi-Scale Analysis Of Jaguar (Panthera Onca) And Puma (Puma Concolor) Habitat Selection And Conservation In The Narrowest Section Of Panama., Kimberly A. Craighead
Antioch University Dissertations & Theses
Over the past two centuries, large terrestrial carnivores have suffered extreme population declines and range contractions resulting from the synergistic anthropogenic threats of land-use change and indirect effects of climate change. In Panama, rapid land use conversion coupled with climate change is predicted to negatively impact jaguar (Panthera onca) and puma (Puma concolor). This dissertation examined the environmental variables and scales influencing jaguar and puma habitat selection by season (annual, wet, and dry), using multi-scale optimized habitat suitability models and a machine-learning algorithm (Random Forests), in the narrowest section of Panama. The models derived from the data of an intensive …
Understanding Community Character As A Socio-Ecological Framework To Enhance Local-Scale Adaptation: An Interdisciplinary Case Study From Rural Northwest Connecticut, Joanna Wozniak-Brown
Understanding Community Character As A Socio-Ecological Framework To Enhance Local-Scale Adaptation: An Interdisciplinary Case Study From Rural Northwest Connecticut, Joanna Wozniak-Brown
Antioch University Dissertations & Theses
Around the world, municipalities are facing new challenges, not the least of which is climate change. This is especially true for rural communities that, for a variety of reasons, will be disproportionately affected by the climatic changes and accompanying policies or programs.
This dissertation, written in manuscript-style, integrates climate change and social-ecological scholarship to address the unique character of rural communities, to communicate the complexity of rural identity through the term "rural character"; and to empower rural communities to incorporate adaptation strategies into their daily municipal operations and planning.
Specifically, this dissertation seeks to answer the following questions: What is …
Positive Organizational Leadership And Pro-Environmental Behavior: The Phenomenon Of Institutional Fossil Fuel Divestment, Abigail Abrash Walton
Positive Organizational Leadership And Pro-Environmental Behavior: The Phenomenon Of Institutional Fossil Fuel Divestment, Abigail Abrash Walton
Antioch University Dissertations & Theses
Climate change is one of the most significant dynamics of our time.The predominant contributor to climate change is combustion of fossil fuels by humans.This study deepened understanding of organizational leaders’ role in enacting one approach to addressing climate change:institutional fossil fuel divestment.The study used a qualitative research design to explore U.S.-based foundation leaders’ readiness to pursue fossil fuel divestment by their institutions.The study examined leaders’ motivations and actions in pursuing divestment, while simultaneously exercising their fiduciary duty to steward institutional assets.Research questions focused on the divestment behavior change process and the outcomes of divestment on leaders and their organizations.Data collection …
From Alarm To Action: Closing The Gap Between Belief And Behavior In Response To Climate Change, Kathryn Laing Doherty
From Alarm To Action: Closing The Gap Between Belief And Behavior In Response To Climate Change, Kathryn Laing Doherty
Antioch University Dissertations & Theses
The degree to which the climate continues to change will largely be determined by choices made by individuals and nations regarding greenhouse gas emissions. Many Americans engage in energy conservation actions. But, the political will in the United States to adopt emissions reduction policies is unlikely to exist without public demand. Therefore, public mitigation actions of individuals (e.g., contacting elected officials in support of emissions reduction) are critical to induce legislative response. The majority of individuals who are most concerned about climate change (the “Alarmed” segment) do not engage in public mitigation actions, but some do. The purpose of this …
Seeing Shifts: Ecologists' Lived Experiences Of Climate Change In Mountains Of The American West, Kimberly Ford Langmaid
Seeing Shifts: Ecologists' Lived Experiences Of Climate Change In Mountains Of The American West, Kimberly Ford Langmaid
Antioch University Dissertations & Theses
This study explores the lived experiences of field ecologists who research the effects of global climate change on mountain species and ecosystems in the American West. The purpose is to generate narrative descriptions of ecologists’ experiences in order to communicate about both the scientific ecology and human ecology of climate change. Twenty prominent field ecologists participated in this study. Interviews with ecologists were transcribed and analyzed using a hermeneutic phenomenological methodology. Eight experiential themes emerged through the process of data analysis, and these themes provide the structure for presenting narratives of ecologists’ experiences. The eight themes are: thinking ecologically, the …
